Photoconductor for electrophotography with phosphorus containing interlayer

Abstract

A separate-function laminate-type photoconductor for electrophotography includes a photosensitive substrate having a subbing layer and a photosensitive layer laminated on the substrate in this order, in which the subbing layer is composed of a resin containing phosphorus in an amount within the range of 30 to 500 ppm by weight based on the resin. The resin for the subbing layer is preferably an epoxy resin. The photoconductor has a high sensitivity, a good ability to electrified and a low residual potential, and gives less variation in its characteristics due to environmental factors to give an image of a good quality constantly.

What is claimed is: 
     
       1. A photoconductor for electrophotography, comprising: an electroconductive substrate;   a subbing layer laminated on the substrate; and   a photosensitive layer laminated on the subbing layer,   wherein said subbing layer is comprised of:   a resin, and   phosphorus from an inorganic source in an amount within the range of from about 30 to about 500 ppm by weight based on weight of said resin.   
     
     
       2. The photoconductor for electrophotography as claimed in claim 1, wherein said resin is an epoxy resin. 
     
     
       3. The photoconductor for electrophotography as claimed in claim 1, wherein the phosphorus is obtained from phosphorus pentoxide, P 2  O 5 . 
     
     
       4. A photoconductor for electrophotography, comprising: an electroconductive substrate;   a subbing layer laminated on the substrate; and   a photosensitive layer laminated on the subbing layer,   wherein said subbing layer is comprised of:   a resin, and   phosphorus pentoxide in an amount within the range of from about 30 to about 500 ppm by weight based on weight of said resin.   
     
     
       5. The photoconductor for electrophotography as claimed in claim 4, wherein said resin is an epoxy resin.
